I'm running Ubuntu 12.04 on a Lenova ThinkPad. I updated a few days ago, and my wireless interface has basically disappeared. I can see where they should be when I click on my internet icon, but they're ghosted out.
I've tried the
/etc/init.d/networking start and the 'service networking start' but I wasn't getting anywhere with either of them.
I found this question: Unable to connect to WiFi network after updates
and tried it out:
cordelia@bug:~$ rfkill list wlan 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: yes cordelia@bug:~$ rfkill unblock wlan Can't open RFKILL control device: Permission denied cordelia@bug:~$ sudo rfkill unblock wlan cordelia@bug:~$ sudo service network-manager restart network-manager stop/waiting network-manager start/running, process 6814
That fixed his wireless, but I still can't get mine to work. And I really don't know why.
My ifconfig looks like this:
eth0 Link encap:Ethernet HWaddr 00:1f:16:0b:5b:b3 inet6 addr: fe80::21f:16ff:fe0b:5bb3/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3892 errors:0 dropped:0 overruns:0 frame:0 TX packets:4116 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3528991 (3.5 MB) TX bytes:582490 (582.4 KB) Interrupt:20 Memory:f2600000-f2620000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:4835 errors:0 dropped:0 overruns:0 frame:0 TX packets:4835 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:390732 (390.7 KB) TX bytes:390732 (390.7 KB) And my lspci: 03:00.0 Network controller: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection
My dad poked around but couldn't find a solution. When I click on the wireless interface it gives me this list of data:
Type: Wireless 802.11
Connection State: Unavailable
IP Address: No IP address.
Connection Speed: Unknown
System Name: wlan0
MAC Address: 00:21:5D:91:28:DA
I don't know what I'm doing wrong or not doing right. Is there anything else I need to try or tell you?
